Serotonin-norepinephrine reuptake inhibitor (SNRI)
Duloxetine dosage guide: how much to take and when
Choosing the right dose of Duloxetine (Duloxetine) is the most important practical decision after starting therapy. Duloxetine is supplied as capsule in 20mg, 30mg, 60mg, and the right dose for a given person depends on the indication, age, comorbidities and tolerance to the active ingredient Duloxetine.
Starting dose and titration
According to the prescribing information, most adults begin Duloxetine at the lowest available strength of 20mg, 30mg, 60mg and titrate up only if symptom control is insufficient and tolerability is good. Higher doses are reserved for selected cases. Older adults, people with renal or hepatic impairment, and those taking interacting medications should usually start at the lowest dose.
When to adjust
Dose adjustment is guided by symptom response and side effect burden, not by arbitrary schedules. Duloxetine inhibits the reuptake of both serotonin and norepinephrine at the synapse, with weaker effect on dopamine. If side effects are limiting at a given dose, going down a step is usually preferred over stopping abruptly. If the response is incomplete after several weeks, a higher dose can be tried under medical supervision.
Frequently asked questions
What is the standard starting dose of Duloxetine? ▾
Most adults start Duloxetine at the lowest strength of 20mg, 30mg, 60mg, with adjustment based on symptom response and tolerance. Older adults and those with reduced kidney or liver function generally start lower. The prescriber decides the exact starting dose for each person.
Can I take a higher dose of Duloxetine if it isn't working? ▾
Higher doses of Duloxetine should only be used after consulting the prescriber. Doubling on your own is unsafe, especially with active ingredients in the Serotonin-norepinephrine reuptake inhibitor (SNRI) class. The prescriber can confirm whether titration is appropriate or whether the medication needs to be changed.
